Dear All, I've been reading much about Guaifenesin for reversing FM. I would like to know people results from taking Guafenesin. I would also like to know if you can find the Guaifenesin Pill at Eckerds, CVS, Wal-Mart or any other common chain store. I would also like to know if the Guaifenesin Cough syrup is just as effective. THANKS!
